Loxodonta africana, the African Bush Elephant. I've waited forever to see the largest land-based animal in the wild and they really look tiny in the massive Serengeti. At least, that's the case until you get close to one of those things and realize how huge they are. When you're used to seeing elephants in the Indian subcontinent you feel that their African relatives would be similar in behavior. Elephants in India need a cautious approach. It is perhaps frequent conflict with men that makes some herds in India aggressive. Charges, mock-charges and tail-twisted flight are all common with wild elephant encounters back at home, but the Serengeti (and Northern Tanzania in general) turned out to be a much different experience. Elephants are calm and at peace with men here and they don't run or charge that frequently. In fact, it is probably safe to say that some of the elephants are rather tame. We had a bull elephant drinking water at our campsite near the Ngorongoro crater and even with people just a few small footsteps away, the bull went about his business and calmly walked out into the wild. It is such a nice experience to watch animals when they aren't feeling scared or feeling the need to attack/defend.
